As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. SDS of cas: 19132-06-0, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 19132-06-0

Intramolecular Pauson-Khand reactions of 1,6-enynes 3a-c with a methylenecyclopropane terminator and a chiral acetal moiety adjacent to the triple bond gave spiro 5a-c in good yields with a diastereoselectivity of up to 6.4:1.The major diastereomer of 5b was converted to enantiomerically pure bicyclo<3.3.0>octane-3,8-dione 8, which showed a negative peak at 287 nm in the CD curve, consistent with an assumed (5R) configuration.Keywords: Pauson-Khand reaction, intramolecular; methylenecyclopropanes, double bond activation in; spirooct-1-en-3-ones>; enentiomerically pure compounds; stereoselection.
